- SPECIFICATION forming part of Letters Patent No. 406,326, dated July2, 1889.

Application filed March 10, 188.

To all whom it may concern.-

- a machine by which fabrics can be thoroughly and quickly gigged, andby which an even nap can be raised upon the goods, as fully describedhereinafter, reference bein had to the accompanying drawings, in which-Figure 1 is a side view of my improved gigging-machine. Fig. 2 is atransverse section on the line 1' 2, Fig, 3, parts being in elevation.Fig. 3 is a plan view. Fig. at is a View of one of the simplest forms ofmy device. Fig. 5 is a view of the machine'by which the fabric is giggedon both sides as it passes through the machine. Figs. 6 and 7 are viewsshowing details of construction, and Fig.8 is a view of a modification.

A is the frame of the machine, and L is the main driving-shaft.

D D are two rollers mounted in suitable bearings (Z (Z, secured to theframe of the machine.

E is a feed-roller mounted in bearings in the frame of the machine andcovered with fine teeth to feed the cloth through the machine, saidroller being provided with a chainwheel 6, geared to a chain-wheel b ona supplementary shaft B by a chain F passing around these chain-wheelsand driving the roller E from the said shaft.

G G Gr are three small rollers adapted to bearings in brackets g,vertically adjustable on the frame A, set-screws g, which pass throughslots in these bracket-s, securing the brackets in the position to whichthey are adjusted.

H H H are three stationary cross-bars, the bars 11 being padded on oneside and the bar H padded on both sides, as shown in Fig. 2 for apurpose described hereinafter.

On each side of the machine is a lever I, pivoted. in bearings i on theframe of the machine. To these levers are attached crossbars J J, havingon each side gigging-teethj, which engage with the cloth as the frame isably faster than the travel of the cloth.

reciprocated. The frame is reciprocated by means of eccentrics K, nearthe ends of the shaft L, the strap of the eccentrics being connected topins 2" on the-levers I. The shaft B is driven from the main shaft Lthrough the medium of the pinion Z and a large gearwheel 0, as shown inFigs. 2 and 3, so that the frame formed by the levers I and cross-bars JWill be reciprocated at a speed consider- The cloth passes over a bar aand under a guideroller 1%. The bar a is provided with a roughenedsurface, for the purpose of placing tension upon the fabric as it passesthrough the machine. I

The cloth is represented in the drawings by the two light lines at, andis fed into the machine in the direction of the arrows, Fig. 2, and itwill be not-iced that the cloth first passes over the bar it, under theroller m over one of the rollers G, down between one of the padded barsII and a gigging-bar J, around one of the rollers D and up between thebar H and a gigging-bar, and over another roller G, and so on, asindicated, until it passes under the roller E, which is the feed-roll ofthe machine. This feed-roller draws the cloth through the machine,keeping tension upon the cloth at all times while it is passing thegiggingframe. The cloth then passes up to and over a roller M, mountedon a bracket on the frame of the machine, this roller M being drivenfrom the roller E by means of a belt M; As the cloth passes from theroller E to the roller M, it is brought into contact with a revolvinggigging-brush N, preferably driven at a higher speed than the roller E,and being also preferably driven from the shaft L by means of a belt N.

P is an inclined board at the rear of the machine, which guides thematerial to the front of the machine after it passes over the roller M.

If necessary, the material can be passed through the machine severaltimes, the num- 9 her of gigging operations to which it is subjecteddepending greatly upon the character of the goods operated upon.

In some cases the multiple gigging-frame may be dispensed with, and aframe may be used, as shown in Fig. 4, in which the gig is placedbetween two stationary bars H H, and instead of being positively mountedon the frame can slide thereon, the eccentric giving practically thesame movement to the gig, and the fabric in this instance being giggedonly twice in its passage through the machine, whereas in the machineshown in Fig. 2 the cloth is gigged four times.

In Fig. 5 I have shown a single roller G and a single feed-roller E, andthe cloth, as it passes through the machine, is gigged on both sides,the two giggin g-bars J J being mounted upon the arm I, one on one sideof the bar II and the other 011 the opposite side of another bar H, sothat the cloth passes between the two stationary bars and the twogigging-bars, being gigged first on one side and then on the other. Thisdevice may be duplicated, if found necessary. By this method of giggingthe cloth itself engages with the teeth of the gigging-bars and not asis usual in this class of machines, in which the teeth have a movementto engage with the cloth. The cloth moves slowly through the machine,and as the gigging-teeth strike the cloth, the cloth continues itsmovement and engages with the teeth, and as the teeth pass away from thecloth they drag with them a port-ion of the fabric and form a napthereon.

As shown in Figs. 6 and 7, I preferably fix the gigging-bars J to theirframes or levers I in such a manner that either set of giggingteeth onsaid bars can be brought into use,

the gigging-teeth being placed on all four sides of the bars, so thatwhen two sets of teeth sets of teeth will engage with the cloth, the

bar being secured in position by tightening the bolts forming its axis,thus providing for the continuous operation of the machine withoutstopping to replace the bars with new or cleaned teeth.

I prefer to use as teeth fine card-clothing, and this clothing ismounted upon strips 8, which'are secured to the bar by means of screwss,as shown in Fig. 7 ,so that the strips can be readily removed and newstrips inserted.

The gigging-bars .I may be round, as shown in Fig. 8, or many-sidedinstead of square, as shown in Fig. 7, so that as the teeth becomeclogged a new toothed surface may be presented by simply turning the barJ, as before remarked in reference to Fig. 6.

The frames or levers I, on which the bars .I are mounted, I prefer toslot longitudinally, (see Fig. 6,) so that the bars may be adjusted toor from the stationary bars H.

I prefer to pad the bars II; but in some instances the padding may bedispensed with, this padding depending, to a great extent, upon thequality and thickness of the goods operated on.

I claim as my invention 1. The combination, in a gigging-machine, of areciprocating frame carrying one or more gigging-bars with teeth upontheir opposite sides, opposite padded backing-bars, and means forreciprocating said gigging-bars between the backing-bars, with feedingdevices for carrying the cloth to be gigged through the machine,substantially as specifled.

2. The combination, in a gigging-machine, of one or more stationarybacking-bars, the reciprocating frame carrying one or more transversebars of round or rectangular crosssection, said bars being provided withreserve gigging-teeth capable of adjustment to working position, meansfor reciprocating said frame, and feeding devices for carrying the clothto be gigged through the machine, sultst-antially as specified.

3. The combination, in a gigging-machine, of the stationary bars II II,guiding-rollers G and D, and the feed-roller E with a reciprocati n ggigging-frame having cross-bars J and teeth on the sides of thecross-bars opposite the stationary bars II II, with means forreciprocating the gigging-bar, all substantially as set forth.

4. The combination, in a gigging-machine, of the gigging-frame composedof bars II II and the reciprocating giggingframe, the guiding-rollers,and feed-rollers with a brush N, situated in the rear of thegigging-frame, and means to reciprocate said gigging-frame,substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHRISTIAN \VOELFEL.
